After 76 years, the issue finally was resolved.
NASA astronomers have uncovered one of the oldest mysteries of the Sun, and that is the reason why the surface of the star 200 times colder than the atmosphere around it. Scientists have wrestled with this mystery 76.
Using a special IRIS Observatory, NASA astronomers have established the reason why the Sun’s corona has a much higher temperature than the visible surface of the star. The average temperature of the upper layer of the Sun is 5.5 thousand degrees while the atmosphere around the star is heated to 200-500 times stronger.
The cause of the phenomenon lies in the magnetic field of the star. According to the theory, it accumulates energy around the Sun, when it becomes too much – there is an explosion. The so-called “heat bombs” and heated up the atmosphere around the sun. That is the reason for the ultra-high temperatures in the Sun’s corona is emitted by energy star.
Note that the anomaly first became interested in astrophysics in the 1940-ies. The fact that the phenomenon was contrary to the laws of physics, and the mystery soon became one of the main problems in astronomy. After 76 years, the issue finally was resolved.
